| Alloy 4047 was originally developed as a brazing alloy (BAIAi-4) or (718) to take advantage of its low melting point and narrow freezing range. In addition, It has a higher silicon conternt than 4043, Which provides for increased fluidity and reduced shrinkage. The alloy produces bright and almost smut free welds. Hot cracking is significantly reduced when 4047 is used as a filler alloy. | ||
